Product development

Scaling eCommerce platform to support 25% monthly users growth

In London developers are in short supply, so the CEO of Heist Studio had difficulties recruiting them and finding resources to scale his business. With global expansion, he wanted to develop a high-performing and scalable eCommerce application to replace the old one. We built a team of seasoned back-end developers with extensive experience in API design.

Solution development

Buidling 250,000 online stores with custom eCommerce platform

Like many startups, SquadLocker was struggling with onshore development costs. Keith, COO, started with web searches and came across different companies in Belarus, Poland, and Ukraine. He decided to work with us due to our company culture, domain knowledge, and team experience.
